Hello everyone, I have a synchronous data bus running at 66 MHz between FPGA and an = ASIC. The trace in question is routed on S1 while the power plane P is split = up. This trace traverses over the split plane in between FPGA and ASIC.=20 S G S P S1 S2 G S3 How can I measure the effect of the Split plane on the integrity of my = signal on the board and what is the usual approach to this problem in such a scenario where crossing the split plane is unavoidable.=20 Any suggestion would be greatly appreciated. Thank you.
